<p>Hi all<br>
What is the difference between <a class="stream" data-stream-id="146212" href="/#narrow/stream/146212-t-compiler.2Fconst-eval">#t-compiler/const-eval</a> and this stream?</p>

<p><span class="user-mention" data-user-id="246518">@Stefan dns2utf8 Schindler</span> I believe the difference is that <a class="stream" data-stream-id="260443" href="/#narrow/stream/260443-project-const-generics">#project-const-generics</a> is focused on stabilising the <code>fn foo&lt;T: const usize&gt;</code> feature and <a class="stream" data-stream-id="146212" href="/#narrow/stream/146212-t-compiler.2Fconst-eval">#t-compiler/const-eval</a> is focused on improving <code>const fn</code> support.</p>
<p>So both const related but one is focused on using them in generics and static dispatch and the other for running general purpose rust code.</p>
